RNA Extraction

Total RNA was extracted using MIRNEASY MINI KIT (Qiagen, Hilden, Germany) according to the manufacturer’s instructions. according to the manufacturer’s instructions. Both left and right eyeballs from one mouse were added into a 2 mL tube containing 700ul QIAzol Lysis Reagent and one 5 mm stainless steel bead (Qiagen, Hilden, Germany). The tissue was homogenized for 2 minutes in a Tissue Lyser II (Qiagen, Hilden, Germany) with a speed frequency of 30 r followed by incubating for 5 minutes.140 µl chloroform was added into the homogenate, shaken vigorously for 15 seconds, and centrifuged for 15 minutes at 12,000 x g at 4 ℃. 280 µl upper aqueous was then transferred into a new collection tube containing 500 µl 100% ethanol. The mixture was loaded into a RNeasy mini‐spin column (Qiagen, Valencia, CA, USA), once with Buffer RWT and twice with Buffer RPE purification. All RNA had been verified by Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA). RNA with OD260/280 > 1.8 and RIN > 7.0 were used for library preparation

About cases

The study included 187 mice (12~18 month) from B6, D2, D2-Gpmnb, B6D2F1, D2B6F1, and 87 advanced intercross BXD strains (about 2 mice per strain). All procedures were approved by the UTHSC Institutional Animal Care and Use Committee.

About tissue

Tissue Harvest

The animals were sacrificed under saturated isoflurane. Eyeballs from the animals were dissected and stored at −80°C until RNA extraction.

About data processing

Generation of RNA-seq data

1 µg of RNA was used for cDNA library construction at Novogene using an NEBNext^® Ultra RNA Library Prep Kit for Illumina^® (cat# E7420S, New England Biolabs, Ipswich, MA, USA) according to the manufacturer’s protocol. Briefly, mRNA was enriched using oligo(dT) beads followed by two rounds of purification and fragmented randomly by adding fragmentation buffer. The first strand cDNA was synthesized using random hexamers primer, after which a custom second-strand synthesis buffer (Illumina, San Diego, CA, USA), dNTPs, RNase H and DNA polymerase I were added to generate the second strand (ds cDNA). After a series of terminal repair, poly-adenylation, and sequencing adaptor ligation, the double-stranded cDNA library was completed following size selection and PCR enrichment. The resulting 250-350 bp insert libraries were quantified using a Qubit 2.0 fluorometer (Thermo Fisher Scientific, Waltham, MA, USA) and quantitative PCR. Size distribution was analyzed using an Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA). Qualified libraries were sequenced on an Illumina Novaseq Platform (Illumina, San Diego, CA, USA) using a paired-end 150 run (2×150 bases). An average of 40 million raw reads were generated from each library.

Read mapping and normalization

Mus musculus (mouse) reference genome (mm11 Mus_musculus.GRCm39, release 104) and gene model annotation files were downloaded from the Ensembl genome browser (https://useast.ensembl.org/). Rows with no gene symbol name were deleted. Indices of the reference genome were built using STAR version 2.5.2b and paired-end reads were aligned to the reference genome. FeatureCount from package RsubRead, version 1.32.4, was used to count the number of read mapped to each gene. Raw counts were then normalized and log2 transformed using function rlogTransformation from the DESeq2 package (version 1.16.1) and an increment was added to the normalized values to make all values positive.
